Xiaomi 13 stuck in fastboot

[Enyrox]

Hello, my phone (Xiaomi 13, on xiaomi.eu_FUXI_OS2.0.104.0.VMCCNXM_15) seems to be stuck in fastboot and the "reboot method" with the power and the volume button doesn't work, it immediately goes back to fastboot.

I was using my phone as usual when suddenly the " - " volume button stopped responding so I decided to reboot my phone to try fix it but not it's even worse.

Can someone help me please ?

1, check if the power button is stuck
2, install ROM via fastboot using the script "- install_upgrade -" without data wipe
